Hi there,
I bought a used TDI with a BEW engine. The car also had a fantastic service history, with regular oil changes every 5k miles or so. The receipts say that the oil used the entire time has been Mobil 1 Synthetic 5w-30. This worries me, as I don't think that's on the approved oil list and may not meet VW 505.01 spec.
The car is sitting at just over 130k miles, and I don't think that the camshaft has ever been inspected. It runs beautifully after replacing the alternator pulley, and it only has occasional, extremely minor hiccups at idle, much like I've felt on almost every other car I have driven. I have no abnormal noises coming from the engine, either.
I have since switched to Liquimoly Top Tech 4100 5w-40. Do you think it would be necessary to pull off the valve cover and take a peek at the camshaft at this time?
